<p>A suction device and a nozzle device that have a simple structure and where, when suction work is performed with a nozzle that is close to or in contact with an object, a fluid is automatically jetted from a nozzle toward the object and the fluid that struck the object can be absorbed. Further, when the nozzle is moved away from the object, jetting the fluid toward the outside of the nozzle is automatically stopped. In a suction device (1), a fluid nozzle (12) for jetting a liquid toward a nozzle opening end is provided in a nozzle (11). When an opening (13) of the nozzle (11) is opened, outside air (300) sucked from the opening (13) into the nozzle (11) overcomes the fluid jetted from the fluid nozzle (12), making it possible that the fluid is sucked together with the outside air (300) without the fluid jetted from the opening (13). When an amount of outside air sucked into the nozzle (11) is reduced by bringing the opening (13) close to or into contact with the object, a fluid jetted from the fluid nozzle (12) overcomes the outside air and is jetted to the object, making it possible that the fluid struck the object is sucked.</p> |
